To aZZ whom it may concern Be it known that I, EDMOND C. ANGEL, a citizen of the United States, and a resident of Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Gaseous-Fuel Mixer, of which the following is a specification.

My invention relates to gaseous fuel mixers for internal combustion engines and its principal object resides in the provision of a device whereby the fuel will be thoroughly mixed and yet will not be obstructed in its passage to the engine.

Further, the invention embodies a gaseous fuel mixer employing a plurality of rotatable elements or agitators so arranged as to mix or agitate the entire cross sectional area of the volume of gaseous fuel passing through the intake manifold of the engine.

Still another object of the invention is to provide a fuel mixer of this character wherein the rotatable elements or agitators are arranged so that their axes will not obstruct the passage of fuel through the manifold.

with the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, construction and arrangement of parts and operations to be more fully described, claimed and illustrated in the accompanying drawing, wherein: I

Figure 1 is a plan view of my improved mixer;

Figure 2 is a longitudinal sectional view taken on line 22 of Figure 1; and Figure 3 is a transverse sectional view taken on line 33 of Figure 1 and illustrating the device associated with a carburetor and intake manifold, parts of which are shown in cross section.

Referring in detail to the drawing wherein like characters of reference designate like parts throughout the several views, the numeral 5 designates a plate or body of relatively great thickness held between the flange 6 of the outlet of the carburetor, indi cated at 7, and the intake manifold designated at 8 in any desirable manner. This plate or body 5 is provided with a central opening 9 of a diameter equal to the diameter of the carburetor outlet and the intake manifold. The body or plate 5 is also provided with a circumferential groove 10 upon its inner face which serves as a mixing or agitating chamber as will be hereinafter pointed out.

Disposed radially with respect to the opening 9 and extending laterally and inwardly from the opposite faces of the body or plate 5 at the edge of the opening 9 are pairs of bearings 11 and rotatably supported between each of these bearings is an agitator or mixing element including a hub 12 and a plurality of angularly disposed blades 13. The latter, during their rotation, pass into the circumferential groove 10.

The hub 12 of each mixer or agitator is revoluble about a bushing 14 supported upon the reduced ends 15 of set screws 16 thread- I wish to emphasize that by providing a plurality of rotatable mixing elements or agitators and mounting the same, as set forth, their axes cannot hinder the passage of gaseous fuel as is the case with devices of this character employing a single agitator or mixer.

It is to be understood that the form of my invention herein shown and described is tobe taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subj oined claims.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is: I

1. A gaseous mixing device to be arranged in the intake manifold of an internal combustion engine comprising a body having an opening of substantially the same area as the cross sectional area of the intake manifold, and a plurality of rotatable agitating elements arranged with their axes adjacent the edge of the opening.

2. A gaseous fuel mixer comprising a body having a central opening and further provided with a circumferential groove upon its inner face that serves as a mixing chamber, and a plurality of rotatable agitating elements journaled at the edge of the opening to pass into the groove during their rotation whereby to cause a quantity of the gaseous fuel to circulate in the groove for thoroughly mixing.

3. In a gaseous fuel mixer for internal combustion engines a body having a central opening to be disposed concentric to the bore of the intake manifold of the internal combustion engine and also provided with a circumferential groove upon its inner face, pairs of parallel bearings disposed radially and extending inwardly from the edge of the opening, and a rotatable agitating element journaledbetween each pair of bearings and arranged so that parts thereof pass into the groove during their rotation.

EDMOND C. ANGEL.
